如何在Django中进行用户的DetailView？

Question

我目前有一个DetailView用于Django的内置功能User.

url(
    r'^users/(?P<pk>\d+)/$',
    DetailView.as_view(
        model = User,
        template_name = 'doors/users/detail.html'
    ),
    name = 'users_detail'
)

但是当我user在模板中访问时,它会显示当前登录的用户,而不是具有pk我传递的用户DetailUser.我是否需要告诉DetailUser将user变量重命名为其他内容？如果是这样,我该怎么做？

Answer 1

django.contrib.auth.context_processors.auth将{{ user }}模板上下文变量设置为request.user或AnonymousUser.因此,它会覆盖{{ user }}DetailView创建的上下文变量:

def auth(request):
    """
    Returns context variables required by apps that use Django's authentication
    system.

    If there is no 'user' attribute in the request, uses AnonymousUser (from
    django.contrib.auth).
    """
    # If we access request.user, request.session is accessed, which results in
    # 'Vary: Cookie' being sent in every request that uses this context
    # processor, which can easily be every request on a site if
    # TEMPLATE_CONTEXT_PROCESSORS has this context processor added.  This kills
    # the ability to cache.  So, we carefully ensure these attributes are lazy.
    # We don't use django.utils.functional.lazy() for User, because that
    # requires knowing the class of the object we want to proxy, which could
    # break with custom auth backends.  LazyObject is a less complete but more
    # flexible solution that is a good enough wrapper for 'User'.
    def get_user():
        if hasattr(request, 'user'):
            return request.user
        else:
            from django.contrib.auth.models import AnonymousUser
            return AnonymousUser()

    return {
        'user': SimpleLazyObject(get_user),
        'messages': messages.get_messages(request),
        'perms':  lazy(lambda: PermWrapper(get_user()), PermWrapper)(),
    }  

您可以通过设置context_object_name来解决此问题.例如,这将启用{{ user_object }}上下文变量,设置为DetailView的用户:

url(
    r'^users/(?P<pk>\d+)/$',
    DetailView.as_view(
        model = User,
        template_name = 'doors/users/detail.html',
        context_object_name = 'user_object'
    ),
    name = 'users_detail'
)
